Brittlestar arms regenerated faster in warmer water. However, they did not do so when the temperature increase was accompanied by ocean acidification conditions. This may have occurred because the brittlestars had to devote more of their energy to maintaining calcium carbonate body parts, as calcium carbonate became undersaturated when the ...

The combined effect of ocean acidification and rising temperature enhanced the sensitivity of a red alga to ultraviolet (UV) radiation. This was reflected in an increased damage rate, decreased repair rate, and decreased ratio of repair to damage in thalli. The findings suggest that ocean acidification and warming will reduce ...

The egg production rate, hatching success, and respiration of a Mediterranean copepod were not affected by ocean acidification conditions. Warming and food availability did have some effects. (Laboratory study)

Spider crabs were not able to fully buffer their internal pH when exposed to ocean acidification conditions for 12 days. Behavior of the crabs was not impaired by ocean acidification conditions or acute heat stress when they happened separately, but it was when both occurred at the same time. (Laboratory ...

The entire Northeast U.S. Continental Shelf was warm in 2012 compared to the period of 1977-1987. Warm conditions penetrating to the ocean bottom over much of the region. Warming was greatest during the late winter in the southern Middle Atlantic Bight, peaking during summer elsewhere. Bottom waters in the Middle ...

This study analyzed changes in phytoplankton and zooplankton on the Newfoundland and Scotian shelves from 1962 to 2003 in relation to changes in oceanography. Three categories of phytoplankton (color, diatoms, dinoflagellates) increased in abundance in the 1990s, and these increases generally persisted into 2001–2003. This is believed to be a ...

This study analyzed thermohaline dynamics of the Gulf of Maine based on data published in 1968. It describes six water masses: Maine Surface Water, Maine Intermediate Water, and Maine Bottom Water as interior water masses; and Scotian Shelf Water, Slope Water, and Georges Bank Water as exterior water masses. ...

The Gulf of Maine's unusual geography and oceanography make it distinct from other continental shelf ecosystems. It has deep basins, shallow offshore banks that limit water flow between the Gulf and the open Atlantic Ocean, strong tidal mixing of it shallower waters, and a seasonal cycle of intense winter cooling, ...
